Zhang Xiaoyun did not eat, but sat quietly next to Wang Xudong and watched the surveillance video carefully.
Five minutes later, the video finished playing.
"Have you found anything?" Zhang Xiaoyun asked quickly.
Wang Xudong was very serious and did not answer Zhang Xiaoyun's words. Instead, he said to the staff who was controlling the computer next to him: "Play it again."
The staff next to him then played the five-minute surveillance video from the beginning again. Wang Xudong began to focus on the surveillance video again. He didn't even notice that the cigarette butt on his hand was about to be burned, and he continued to burn it on his hand.
Looking at Zhang Xiaoyun next to me, she was almost suffering from obsessive-compulsive disorder. She wanted to help Wang Xudong get it, but she gave up on seeing Wang Xudong's serious look.
"Stop." Suddenly, Wang Xudong shouted, and the screen suddenly stopped.
Zhang Xiaoyun quickly looked at the screen, but there was nothing on the screen except countless "heads". She quickly asked Wang Xudong: "What did you see?"
"Zoom in." Wang Xudong said.
Then the screen started to zoom in.
"Zoom in again, keep zooming in, okay, that's it." Wang Xudong commanded, then smiled, suddenly shouted, and quickly threw away the cigarette butts that were burning in his hands, and scolded Zhang Xiaoyun: "You
This guy, I even burned my hands and you didn’t remind me.”
Zhang Xiaoyun ignored Wang Xudong and looked carefully at the picture Wang Xudong asked to enlarge. Several "heads" crowded together appeared in the picture. Zhang Xiaoyun stared at these people for a long time and did not find anything wrong. Asked
Asked Wang Xudong: "What did you find? Is there anything wrong with these people?"
Wang Xudong stood up, walked to the projector, raised his hand and tapped the head of a man in the picture and said: "This is the person you are looking for, just follow him and find him."
"Is he the suspect?" Zhang Xiaoyun also stood up and walked to Wang Xudong and asked.
"Yes, that's him." Wang Xudong nodded, then walked directly to the conference table, opened the lunch box, picked up the chopsticks, and started eating.
Zhang Xiaoyun has been standing in front of the projector and carefully studying the "suspect" mentioned by Wang Xudong. After watching it for a long time, she still did not find any doubts.
"Why him?" Zhang Xiaoyun finally couldn't help it anymore and came over and asked Wang Xudong.
"Why are you the same as one hundred thousand whys today?"
"Tell me, why do you think it's him?" Zhang Xiaoyun continued to ask.
"I'm so hungry. Can you let me finish eating first and then talk about it?" Wang Xudong said.
Zhang Xiaoyun walked over and directly covered the lunch box that Wang Xudong was eating and put it aside, and said: "Please explain to me clearly first, why do you think it is him?"
"You, I've been helping you with your work all morning, and now you don't even give me food. Are you Huang Shiren?" Wang Xudong stood up very dissatisfied, then walked to the projector and faced it.
The staff in front of the computer said: "Shrink the screen to normal size."
"Look now, how is this person different from others?" Wang Xudong asked Zhang Xiaoyun.
Zhang Xiaoyun walked over again and stared at the screen closely for several minutes. Then she shook her head and said, "I don't know. I didn't find anything different. I think he is just like everyone else and is normal."
"It seems that this person's disguise is very successful. At least he has completely deceived you." Wang Xudong said, and then said: "Pay attention to his expression."
"Expression?" Zhang Xiaoyun was a little surprised. It was the first time that someone had an expression on someone investigating a case.
"Yes, it's the expression. Look at other people's expressions. How are they different from his? Let me ask you first, who are the people who usually come to this place? And they are from this time period.
." Wang Xudong asked Zhang Xiaoyun.
"Well... they all come here to shop and eat. The snacks here are very famous in the entire Donghai City. Every day, many people come here to have some snacks after shopping, that's why there are so many people here."
"Yes, your analysis is correct. In this place, at this time, there are only two types of people who appear here. The first type comes here to eat with the mood of shopping. Since they are here for shopping, they should not be the same.
People, at least two or more people, rarely go shopping alone, especially a man shopping alone. Of course, it is not ruled out, but the mood of people who come to go shopping should be quite relaxed, right? Even though this place is a bit crowded
There are many, and the mood should be quite happy and joyful. The second type of people are those who come here specifically to eat, or who come here specifically to buy something to eat and then pack it back for their friends or lovers. This kind of person comes here specifically.
People who buy things here are either in a hurry to get back, or they are more or less impatient when they encounter such a crowded situation, and they may also have a bag in their hand.
Things to pack.”
"Go and see if the other people meet the characteristics I mentioned. They are either a few people shopping together, or they are eating with something in their hands, or they are eating something in their hands. Of course
, there are also people who don’t eat, but there are some traces of grease on the corners of their mouths. People who don’t have these, the expressions on their faces are either relaxed, happy, anxious or irritable. Take a look, don’t you?” Wang Xudong continued.
He pointed at the person on the screen and said.
"But look at this person, is he? He is alone. He doesn't carry anything in his hand, and he doesn't eat anything. The most important thing is his expression." Wang Xudong said.
"What's wrong with his expression?" Zhang Xiaoyun still didn't see anything.
"His expression is too calm. If it were you, in such a crowded situation where you can't walk, could you maintain such a calm mood?" Wang Xudong asked Zhang Xiaoyun.
When Zhang Xiaoyun heard this, her pupils suddenly dilated and she quickly stared at the man's expression.
"Zoom in, zoom in a little bit." Zhang Xiaoyun asked the staff to enlarge the picture.
"Who can maintain such a calm mood in this kind of environment? There can only be one way, that is, he has known this situation for a long time, and this kind of environment is what he needs." Wang Xudong analyzed.
"Of course, it would be too hasty to conclude that he is a suspect just by using this expression. He has another fatal flaw," Wang Xudong continued.
"What?" Zhang Xiaoyun asked quickly after hearing this, and then looked carefully to see where the flaw was.
"A person's clothes can be changed, a person's appearance, height, etc. can be faked, but there is one thing that cannot be disguised." Wang Xudong said.
